i used to play drums. before that the doctors told me i would never play drums, the injury in my arm, they lose feeling. can't be swinging around. the founder of the wounded warrior project, and another guy, john roberts you. got to play, man. got to do something. >> you defied the doctors? >> they found a drum set. i don't know, found one last minute. ended up on stage, no music, no backing music, get up there and play. >> what do you think? what is the healing effect of music? what do you think about it resonates and gets you through? >> a good example. after i played. another guy got up there and played a guitar with a prosthesis. once you see something like that it inspires you to want to do some more. we decided we should do wounded warrior band. i took the idea and went forward with it. i realize there is more than just having a band for wounded warriors, we can inspire, help empower other wounded warriors, using the music as a healing tool. >> that's what you use to start rock for recovery program.
